How To Descale Breville Coffee Maker The Right Way

The water used to brew coffee causes mineral buildup inside your Breville coffee maker. While not toxic, this buildup can impact the machine’s water flow, temperature and performance. It can affect the taste of your cup of coffee too. Descaling is a deep machine cleaning that removes mineral deposits to extend the life of your brewer. Keep reading to find instructions on how to descale Breville coffee maker models like the Precision Brewer or Grind Control using a commercial descaling solution.

How Often To Descale Breville Coffee Maker

In addition to regular cleaning, a good rule of thumb is that a you should descale your coffee maker after 3 months. Both Breville coffee makers have an LCD screen. The descale alert will be shown there to remind you.

You need to descale every 3 months whether you are using filtered water, bottled water or tap water with a low to normal mineral count. You will need to clean your machine more often if your tap has “hard water.” That means it contains higher level of minerals. If you are not sure about the level of minerals in your water, you can always get a low-cost water testing kit.

You should also descale if you are having any of these issues with your Breville coffee maker:

  • Produces a lot of steam while brewing
  • Runs for extended periods with only steam output
  • Does not use the full amount of water in the water tank
  • Brews slowly

Can You Descale Breville Coffee Maker With Vinegar?

You should not use water and vinegar solution to descale Breville coffee machines. White vinegar contains 5-8% acetic acid. This type of acid can wear down stainless steel and cause your machine to leak. Plus, vinegar cannot remove oils left by used coffee beans.

Instead, the best way to descale your coffee maker is with one of the below commercial solutions. They have safe and effective types of acids that won’t damage your machine.
